### Quick Start: Dimension Toolbar

Quick Start Dimension toolbar

The Dimension toolbar lets you perform geometric measurements and geometric tolerance checks. With the exception of the Key-In dimension, this toolbar contains all the dimensions from the normal PC-DMIS Dimension toolbar. See "Dimension Toolbar" in this chapter.

The Quick Start Dimension toolbar only creates legacy dimensions. It does not create the new Feature Control Frame dimensions.

About Geometric Measurements | About Geometric Tolerance Checks
Geometric measurements are used in the following circumstances:

- When dimensions involve two elements (such as distances and angles).

- When dimension elements are not measurable (such as corners).

- When dimension measurements can be obtained by using geometric calculation procedures (intersections, projections, and / or middle elements).

In each geometric relationship between two elements, a third element is created (point, circle, line, or plane). The default output format of the calculated element includes the most meaningful dimensions.

Geometric relationships are not to be confused with geometric tolerances. Geometric tolerances are used to check the functional requirements of a feature. Functional requirements are feature characteristics that ensure sufficient assembly, safety, appearance, performance etc. Geometric relationships, as used in PC-DMIS, are not sufficient to ensure functional requirements because they do not utilize the full extent of datum theory.

Geometric tolerance checks test the location, orientation, profile, runout, or form error of a feature (checked feature) relative to a datum reference frame (as applicable).

The following checks are available:

- Orientation checks: test for errors of parallelism, perpendicularity, and angularity.

- Location checks: test for errors of coaxiality, and concentricity, location, and position.

- Profile checks: test for errors of profile form or profile, relative to the current alignment.

- Runout checks: test for errors of total runout of a circle, cylinder, or plane.

PC-DMIS inserts a dimension of the resulting geometric tolerance check between two elements into the Edit window.
